Heat Affected Zone in Surfacing Chromium Ledeburitic Steel
Repair welding is not used enough in the industry 1 . One of the reasons for this lies in the insufficient and unrealiable knowledge in many segments of this area. A very important part is having appropriate knowledge of metallurgical processes in heating of the base material 2-4 . Unsuitable heating deteriorates the microstructure as it reduces toughness and fracture behaviour of the weld 5 . ...
متن کاملThe softened heat-affected zone in resistance spot welded tailor hardened boron steel: a material model for crash simulation
A hardness-based model for tailor hardened boron steel is presented that takes into account the softened heat-affected zone of resistance spot welds. The computational model is designed for crashworthiness simulation of fully and partially hardened components obtained by tailored tooling. Five different hardness grades of 22MnB5 are used for model calibration. The proposed model is validated wi...
متن کاملCreep and Fatigue Interaction Behavior in Sanicro 25 Heat Resistant Austenitic Stainless Steel
Sanicro 25 is a newly developed advanced high strength heat resistant austenitic stainless steel. The material shows good resistance to steam oxidation and flue gas corrosion, and has higher creep rupture strength than other austenitic stainless steels available today. It is thus an excellent candidate for superheaters and reheaters for advanced ultra-super critical power plants with efficiency...

متن کاملProperties of Boron Steel after Different Heat Treatments
In this article boron steel is analyzed on the example of steel grade B27. In view of the fact that steel is supplied in a state after hot rolling, and the choice of a suitable heat treatment is left to the buyer steel were examined after conventional heat treatments. Steel was studied in state as delivered, after normalization, after quenching and after quenching and tempering at different tem...
