Abstract


The purpose of this research is to know the effect of Heat Treatment Hardening-Tempering Alloy AlMgSi–Fe12% foundry result to hardness and toughness. The test was carried out on raw material and material test specimen after obtaining Hardening heat treatment at 600and quenching with SAE 20 oil medium. While Tempering variation at temperature 200, temperature 250and temperature 300with detention time for 15 min at each temperature, each heat treatment. Hardness testing method is done by standard micro Vickers test method with 100 gf loading. The result of raw material testing for hardness value is 60,92 VHN. Test results after heat treatment process at temperature 200cause hardness value increased by 63,50 VHN. At temperature 250cause hardness value decreased to 59,94 VHN. At temperature 300cause hardness value increase to 76,98 VHN


Keywords
