Influence of Hot Working on the Properties of the Ti 6A1 4V Alloy with Special Regard to Heavy Sections

  • Axel Gerhardt
  • Willy Knorr


During the first years of industrial production of semis of titanium alloys, hot working was carried out in a way to achieve a fine grained microstructure with equiaxed alpha and intergranular beta (1). Heating and heat treating in the beta field was believed to be detrimental to the quality of the products because of the grain growth. A reduction by hot working of 80 % at 950°C or of 30 to 50 % at 900°C was considered necessary to obtain the desired grain refinement of the Ti 6A1 4V-alloy (2).
