针对某项目锻造工具V型砧对棒料整形工艺的特殊性要求,在原90°夹角V型砧的基础上,进行了结构改进设计,设计了135°夹角的V型砧,使其能够满足V型砧对棒料的整形工艺的要求。基于forge软件对棒料在两种V型砧上的整形成形进行了数值模拟,主要包括棒料的成形效果、棒料成形后的等效应力、应变场;同时,对棒料成形过程中V型砧在热应力和压应力的耦合作用下对砧面的影响进行了模拟,主要包括V型砧所受的耦合等效应力及其成形过程中砧面的磨损。通过模拟结果对比及理论分析,得出了135°夹角V型砧的结构设计不仅能满足工艺要求,而且其所受的应力、应变及磨损较90°夹角的V型砧更小。

通过设计正交试验,利用forge仿真分析,获得空心齿轮轴旋锻成形的优化工艺参数组合,并对试制样件进行了显微组织和显微硬度的物理检验。通过正交试验获得的最终优化方案为：坯料的初始温度为830℃,轴向相对送进量为0.05 mm,坯料转速为76 r·min-1,锤头径向压下量为2 mm,锤头径向速度为7.5 mm·s-1。物理检验表明：随着变形量的增加,空心齿轮轴的晶粒越细化,从表层向内晶粒细化先增强后逐渐减弱;旋锻成形使空心齿轮轴获得了纤维组织,提高了致密性;由于第2台阶处径向截面的变形比第1台阶处大,所以第2台阶处的表面显微硬度比第1台阶处大。

A high-performance Mg-4.9Gd-3.2Y-1.1Zn-0.5Zr alloy has been fabricated by multidirectional forging(MDF)after analyzing its compression behavior.The as-homogenized alloy exhibits a high activation energy Q of deformation(~285 kJ/mol).The size of DRXed grains after compression tends to decrease as the Z-H parameter(Z)increases,showing a grain size exponent m of~4.0.Lamellar LPSO phases,kinking deformation,and bimodal microstructure are detected at the relatively low compression temperature of 350 and 400℃,while sufficient DRX can be achieved at 500℃,accompanied by the dissolution of lamellar LPSO.According to the processing maps,MDF was successfully conducted under an appropriate condition.After peak-aged at 200℃for 78 h,the MDFed billet exhibits a tensile yield strength(TYS)of 331 and 305 MPa at room temperature and 200℃,respectively.The high strength mainly results from the combination of fine grains,low Schmid factor for basal slip,sufficientβ’ageing precipitates,and directionally arranged interdendritic LPSO phases,etc.This paper provides a feasible way for the fabrication of high-performance,low-RE-content,and large-scale Mg components for industrial production.

This paper investigated the high cycle fatigue behavior of a forged Mg-7Gd-5Y-1Nd-0.5Zr alloy with different stress concentration factor(Kt),under different stress ratio(R),and along different loading direction.The smooth specimen(Kt=1),under R=0.1 and along longitude direction,shows a high fatigue strength of 162 MPa at 107 cycles.The fatigue behavior of the forged Mg-7Gd-5Y-1Nd-0.5Zr alloy exhibits a high sensitive to the notch.Moreover,change of stress ratio from 0.1 to−1 may also result in a bad fatigue property.The flux inclusions were elongated along longitude direction and/or transverse direction during the forging process of the Mg-7Gd-5Y-1Nd-0.5Zr alloy.The interface between the flux inclusion and the matrix may debond and serve as the crack initiation site during the fatigue loading process,leading to the deterioration of the fatigue property along thickness direction and a high anisotropic fatigue behavior between longitude direction and thickness direction.
