摘要

用DIL850L相变Φ4mm×10mm小试样模拟φ26mm 60Si2CrVAT钢(/%:0.60C、0.63Mn、1.50Si、1.08Cr、0.14V)870～950℃淬火试验。结果表明

随淬火温度提高

钢残余碳化物减少

950℃淬火晶粒长大明显

择优选取910℃为淬火温度。生产检验条件下

采用910℃40 min淬火

420℃ 90 min回火

可获得较佳的综合力学性能-即抗拉强度(R

)1940 MPa

屈服强度(R

p0.2

)1 740 MPa

伸长率(A

)9.5%

断面收缩率(Z)36.5%。

Abstract

The quenching examination of Φ26 mm rod of steel 60Si2CrVAT (/% : 0.60C

0.63 Mn

1.50Si

1.08Cr

0. 14 V) at 870 - 950 °C is simulated by DIL850L phase transition instrument with Φ4 mm x 10 mm small specimen. Simulated test results show that with quenching temperature increasing

the residual carbide in steel decreases

and quenching at 950 Y the grains coarsen obviously

therefore the selected optimum heating temperature for quenching is 910 °C. In condition of production examination

with optimum heat treatment process i. e. quenching at 910 °C for 40 min and tempering at 420 ℃ for 90 min

it is available for steel to get optimum comprehensive mechanical properties i. e. tensile strength R

- 1 940 MPa

yield strength R

p0.2

- 1 740 MPa

elongation A

- 9. 5% and reduction of area Z- 36.5% .
