摘要/Abstract

摘要： 采用EB一次熔炼制备的TC4合金扁锭直接进行轧制,对不同轧制火次板材热轧态及退火态显微组织与力学性能进行了研究。结果表明:TC4合金扁锭经过1~3火次直接轧制,粗大铸态组织不断破碎,等轴α相含量逐渐增加,尺寸不断减小,各火次板材力学性能均满足标准要求。随着退火温度增加,各火次成品板材抗拉强度和屈服强度呈下降趋势,伸长率先增加后减小,经850 ℃退火后TC4合金板材可以获得最佳的强塑性匹配。EB一次熔炼扁锭直轧TC4合金板材工业化批量生产中退火温度推荐使用700~850 ℃,显微组织与力学性能可以达到锻坯制备的板材水平。

Abstract: TC4 alloy slab prepared by one -time EB melting was directly rolled,and the microstructure and mechanical properties of the hot rolled and annealed alloy sheet with different rlling times were studied.The results show that after 1 -3 rounds of direct rlling,the coarse as-cast micorstructure of the alloy is broken continuously,the quantity and the size of equiaxed a phase is gradually increased and reduced,respectively,and the mechanical properties of each rlling round sheet meet the standard requirements.With the increase of annealing temperature,the tensile strength and yield strength of the finished products of each rolling round show a downward trend,and the elongation increases first and then decreases.After annealing at 850 C,the TC4 alloy sheet can obtain the best combination of strength and toughness.The anneal temperature in the industrial batch production of EB primary melting slab direct-rolling TC4 alloy sheet is recommended to use 700-850 C,and the microstructure and mechanical properties can reach the technical requirements of the sheet prepared by forging billet.
