摘要

为获得性能较优的马氏体基体同时避免过大残余应力的形成

研究了淬火方式对高硼合金组织、力学性能及残余应力的影响。采用空冷和油冷两种淬火方式调控合金基体组织和残余应力

进而分析了合金在不同淬火方式下的力学性能和残余应力的变化规律。实验结果表明:热处理后

基体由珠光体转变为马氏体

进而促使合金宏观硬度从铸态下的HRC42.73提高至空冷下的HRC55.31和油冷下的HRC57.18

增幅分别为29.44%和33.82%

同时合金中残余应力从铸态下的-307.66 MPa增至空冷下的-407.35 MPa和油冷下的-462.21 MPa。与油冷方式相比

空冷方式下合金宏观硬度虽略有降低

但形成的残余应力较小

进而降低了合金的淬裂倾向。综上所述

在空冷方式下

高硼合金既可获得较优的力学性能又可避免过大残余应力形成

显示出更优的性价比和应用前景。

Abstract

Effects of quenching methods on microstructure

mechanical properties and residual stress of the high boron alloy(Fe-2.0wt%B alloys)are investigated to obtain martensite matrix with better properties and avoid formation of excessive residual stress. The mechanical properties and residual stress of the alloy are regulated and analy-ed by applying different quenching methods. Results show that after heat treatment

the matrix is transformed from pearlite to martensite

which promotes the macro-hardness of the alloy from HRC 42.73 in as-cast condition to HRC 55.31 in air-quenched state and HRC 57.18 in oil-quenched state. The increase is 29.44% and 33.82%

respectively. Meanwhile

the residual stress in the alloy increases from -307.66 MPa in as-cast state to -407.35 MPa in air-quenched state and marco hardness -462.21 MPa in oil-quenched state. A comparison with the oil-quenched alloy shows that the air-quenched alloy has slight reduction in macro hardness

but has relatively smaller res
