一引言合金的再结晶图是制定合金热加工和形变热处理等工艺的重要依据。对再结晶图的测定,国外早有开展,国内这方面的工作进行得较少。我们用金相法及X射线分析测定了GH132合金的再结晶图。实验用料系采用电弧炉加真空自耗熔炼。二实验方法 1 试样的切取和热压变形试样是在该合金90毫米的方坯上切取,加工成Φ18×20毫米的圆柱体。试样两端车有0.7毫米深的凹坑,以储存润滑剂玻璃粉。为尽可能得到均匀变形,采
I. INTRODUCTION Alloy recrystallization diagram is to develop an alloy heat treatment and deformation heat treatment process important basis. The determination of recrystallization map has long been carried out in foreign countries, and the domestic work in this area has been carried out less. We used the metallographic method and X-ray analysis of GH132 alloy recrystallization. Experimental materials used arc furnace plus vacuum consumable melting. Two experimental methods 1 sample cut and hot deformation specimens are cut in the 90 mm billet alloy, processed into Φ18 × 20 mm cylinder. Both ends of the car have 0.7 mm deep pits to store the lubricant glass powder. To get as uniform deformation, mining
