Abstract

Analisa perambatan retak fatik stainless steel 304 yang dilapisi aluminium dengan metode hot-dip secara ekperimen dan numerikal untuk mengetahui perubahan sifat mekanik pada SS304 serta memprediksi hasil uji fatik secara metode numerik yang berbasis program CFD dengan hasil secara ekperimen. Hasil simulasi siklus perambatan retak fatik menunjukkan hasil yang sama. SS 304 dengan difusi 1 jam memiliki siklus terpendek yaitu pada data simulasi terjadi retakan di siklus 8778 dengan Panjang retak 0,703 mm, sedangkan untuk hasil eksperimen retakan terjadi di siklus 5000 dengan panjang retak 0,267 mm. Lalu SS304 tanpa pelapisan memiliki siklus terpanjang yaitu, retakan pada hasil simulasi terjadi di siklus 20351 dengan Panjang retak 0,6787 mm, sedangkan pada data hasil eksperimen awal retakan di siklus 8700 dengan Panjang retak 0,6 mm. Berdasarkan analisis laju perambatan retak fatik dan tegangan, pemberian perlakuan difusi pada SS304 memberikan dampak baik untuk umur kelelahan maupun tegangan untuk merambatkan retak. Kekuatan dan plastisitas SS304 terdegradasi oleh perlakuan aluminisasi. Setelah perlakuan, SS304 menunjukkan keuletan yang lebih tinggi dan kekuatan yang lebih rendah.

Abstract

Medan magnet eksternal dapat meningkatkan kualitas dari hasil pengelasan TIG. Penelitian ini bertujuan untuk mengetahui pengaruh medan magnet eksternal dalam proses pengelasan TIG. Material yang digunakan dalam penelitian ini adalah baja SS400. Proses pengelasan menggunakan TIG (Tungsten Inert Gas)  dengan variasi arus 70 A, 80 A, 90 A, dan 100 A serta menggunakan tambahan 2 magnet eksternal jenis Neodymium. Pengujian hasil pengelasan berupa struktur makro, mikro, uji kekerasan vickers dan uji tarik. Hasil pengujian struktur makro menunjukan beberapa cacat hasil pengelasan seperti Porositas, Incomplete Penetration, Underfill, dan Distorsi. Sedangkan hasil pengujian struktur mikro menunjukan pada base metal terdapat struktur jenis Ferrite dan Pearlite. Bagian HAZ terdapat struktur jenis Ferrite, Pearlite, dan Martensite. Hasil pengujian tarik paling tinggi terdapat pada sambungan pengelasan TIG tanpa menggunakan magnet dengan arus 100 A yaitu sebesar 368,234 MPa. Hasil pengujian kekerasan paling tinggi terdapat pada sambungan pengelasan TIG menggunakan magnet dengan arus 100 A yaitu sebesar 176,712 HVN. Penggunaan magnet eksternal dapat menghasilkan penetrasi besar saat proses pengelasan dan mengahasilkan sambungan las yang baik. Sebaliknya, hal tersebut dapat berakibat buruk terhadap hasil pengelasan jika jarak busur listrik dengan material tidak tepat, dan torch tidak bergerak sesuai pada jalur pengelasan.

Abstract

The development of technology in enhancing the mechanical properties of materials, such as hardness in metals, has progressed rapidly, particularly in steel. Based on its carbon content, carbon steel is classified into three categories: high-carbon steel, medium-carbon steel, and low-carbon steel. Low-carbon steel contains carbon in the range of 0.04% to 0.30%, one of which is AISI 1020 steel. This study aims to determine the effect of varying intercritical annealing temperatures on the microstructure and hardness of AISI 1020 steel using a saltwater cooling medium. The heating process was conducted using a furnace for 3 hours at different temperatures of 673°C, 723°C, 773°C, 823°C and 873°C. The tests performed included microstructure analysis and hardness testing. The hardness test was conducted using a hardness tester with the Vickers method, while the microstructure analysis was carried out using a trinocular metallurgical microscope. The results showed that the formed phases remained the same as in the initial specimen, consisting of ferrite and pearlite. The highest hardness value was obtained from the specimen heated at 823°C, reaching 243.49 HVN, while the lowest hardness value of 184.33 HVN was recorded in the initial specimen without heat treatment.

Abstract

The percentage of NaOH is one of the parameters that greatly affects the sisal fiber composite (Agave Sisalana). The purpose of this study was to observe and analyze the effect of the percentage of NaOH on the tensile strength of sisal fiber composites (Agave Sisalana). The materials used are sisal fiber (Agave Sisalana) and polyurethane resin at various percentages of NaOH, namely without treatment (0%), 4%, 7%, and 10% with soaking time for 2 hours and drying in the sun for a maximum of three days or until the fiber is completely dry. Composite manufacturing was carried out using the compression molding method for 24 hours at a pressure of 50 bar. The tests carried out in this study were tensile tests referring to the ASTM D 638 standard. The percentage of NaOH without treatment (0%) has the lowest maximum tensile value of 6.688 MPa, while the percentage of 7% NaOH has the highest maximum tensile strength value of 11.821 MPa. Then, the percentage of NaOH without treatment (0%) has the lowest maximum elastic modulus value of 0.072 GPa, and the highest maximum elastic modulus value of 0.152 GPa is also found at 7% NaOH percentage.

Abstract

Temperature is one of the parameters that is very influential in the process of making HDPE matrix composites. This study aims to determine the effect of variations in heating temperature on tensile strength and bending strength and to analyze the fracture structure of HDPE composites. The materials used in this study were HDPE plastic from used bottles, coconut fiber and Sansevieria fiber with a composite ratio of 90:5:5. The process of making HDPE composites is carried out using the hot press compression method. The pressure used is 30 bar for 30 minutes. The temperature variations used are 150ºC, 160ºC, 170ºC, 180ºC, and 190ºC. This study conducted two tests, namely tensile testing and bending testing using the Universal Testing Machine. The tensile testing process uses the ASTM D 3039 standard and obtains the highest results on specimens of 170ºC with a tensile strength value of 509.80 MPa. The value of tensile strength has increased and decreased. The bending test process was carried out according to the ASTM D 790 standard and the highest results were obtained on the 170ºC specimen with a value of 90.99 MPa.

Abstract

The use of external magnetic fields is very influential in TIG (Tungsten Inert Gas) welding because it can disrupt the stability of the electric arc formed between the tungsten electrode and the base metal. Magnetic fields can cause the arc to distort or shift, resulting in uneven and low quality welds. TIG (Tungsten Inert Gas) is a welding method that uses a non-melting tungsten electrode to produce a weld. This study aims to determine the effect of external magnetic field on the quality of TIG welding results. This research uses the TIG (Tungsten Inert Gas) welding process on low carbon steel material with speed variations of 4 mm/s, 6 mm/s, 8 mm/s and 10 mm/s and uses 2 Neodymium type external magnetic fields. Tests carried out on the results of welding joints are Vickers hardness test, micro & macro structure test. The highest hardness test value was obtained in the 4 mm/s welding speed variation using 2 external magnetic fields with a hardness value of 187.388 HVN. Microstructure testing shows that the base metal contains ferrite and pearlite structures. In the HAZ (Heat Affected Zone) area there are ferrite, pearlite and martensite structures. Macro structure testing shows several welding defects, including porosity, imperfect penetration, underfill and irregular surface. The use of two external magnetic fields can affect the results of TIG welding itself, such as deepening the penetration of welding so as to produce a good welding joint. Some things you should pay attention to if you don't want welding defects to occur are paying attention to the distance between the electric arc and the material, and the torch must be parallel to the welding line.
