Abstract

Aluminium is a light metal which has a very good physical and mechanical properties and it easy to be formed. Casting of aluminium posses some advantages high conductivity and low melting point, enables applied permanent mold too. Material that is used to make mold is from special steel, and when casting process, after aluminium-mag-nesium alloy melting will be poured in mold hence after the permanent mold heated in va-rious temperature which has been determined that is, 300 oC, 350 oC and 400 oC. Heat-ing of mold at this research meant to know how far the influence is happened to mechani-cal properties from Aluminium-Magnesium alloy (series 5xxx) especially tensile strength, hardness and transformation of microstructure. From result of research which to be got best tensile strength value to draw alloy Aluminium-Magnesium (Al-Mg) at 350 oC tem-perature equal to 11,11 kg/mm2 and highest hardness at 350 oC temperature equal to 101,64 HB (Hardness Brinnel) while microstructure that is very homogen also there is at temperature 350 oC.

Abstract

Welding is a fabric Welder i.e a fabrication process that applied to joint metal material by using temperature dissociation energy of diatomic. Up to this day, welding has been used widely on joining steel and engine constructions. The influence of thermal cycle on welding causes metallurgical changes i.e residual stress and changes of mechanical characteristics (hardness, strength tensile, reconnaissance of macro and micro structures) on the result of low carbon steel weldment. This research was done to obtain the proper treatment for normalizing weldment result on different current to mechanical character. The value of hardness and strength tensile is best obtained after normalizing process at temperature of 8600C is at the current of 140A with hardness mean value of 78,67 HRB ( weld), 73,89 HRB ( HAZ) and 70,11 HRB ( mains), while strength tensile is 45,835 Kgf/mm2.

Abstract

Composite material especially with fiber reinforcement starts growing rapidly with existence of requirement of light and strong material. Beside that, it is easy to be formed and resistant to corrosion. In this last decade, composite material using natural fiber has been implemented by the European automobile producers. Based on those considera-tions research about composite using kenaf fiber as reinforcement material big strength of mechanic for each varation. (1) Kenaf fiber without cleaning, (2) Kenaf fiber with soaking in NaOH for an hour,(3) Kenaf fiber with soaking in NaOH for two hours and with material matrix polyester.Based on the calculation and experimental analysis soaking in NaOH and bedding of Acrylic increase the mechanical properties. So composite resin polyester as matrix with treatment is much better than without treatment.
