Influence of Heat Treatment on the Mechanical Properties in Various Weld Zone of the Structural Alloy Steel
- 발행 : 1985.06.30
초록
To investigate the influence of annealing heat treatment on the mechanical properties at the various weld zone, an experimental study was performed for the structural alloy steel. The results obtained from the experimental works are as follows: 1. Hardness and tensile strength showed the highest value at the heat affected zone, which was 5mm apart from bond zone. With increasing of annealing temperature, hardness and tensile strength were decreased at every weld zone, and bound in heat affected zone was increased. 2. Impact strength was the highest at the filler metal, and increased with increment of annealing temperature at filler metal and base metal. However, both at bond and heat affected zones, impact strength was increased from
