THERMAL TREATMENT IMPACT UPON STRUCTURE, PROPERTIES AND PHASE STRUCTURE OF STEEL 10G7M3S2AFTYU WELD WITH POWDER WIRE
Abstract and keywords
Abstract (English):
There are investigated peculiarities of hardening through ageing of steel 10G7M3S2AFTYu weld with powder wire. It is defined that ageing at the temperature of 550ºC during 6 hours ensures the highest degree of strengthening of ferrite steel 10G7M3S2AFTYu. It is proved that the mechanism of steel strengthening as a result of ageing is determined with the Ti2CN, V1.98Ti0.02, VC combinations mainly.

Keywords:
welding deposition, ageing, hardness, disperse strengthening, phase composition
