The New Way Out of Non-Criminal Punishment Measures under the Policy of Tempering Justice with Mercy

宽严相济刑事政策下我国非刑罚处罚措施的新出路

Tempering treatment resulted in formation of tempered martensite and the spalling resistance under repeated strong impact abrasion working conditions was largely improved.

在反复强力冲击工况条件下，回火得到回火马氏体，抗冲击剥落能力大为增加。

At the same tempering time and tempering temperature, as the quenching temperature rise, the corrosion resistance of the samples decreased. But under quenched at 930 ° C for 30 minutes, the best comprehensive performance can been obtained.

随着淬火温度的增加，相同的回火温度与回火时间的试样的力学性能在930°C淬火时达到最高，而耐蚀性能则不断降低。

The results showed that two of surfacing layers under 850 ℃ air cooling, 850 ± 5 ℃ oil cooling and 400 ℃ tempering had higher hardness and better wear corrosion resistance, and the technological processes were simplified as well.

结果表明，两种硬质合金堆焊层经850℃空冷、850±5℃油淬+400℃回火后，均具有较高的硬度和优异的耐腐蚀磨损性能，且简化了表面处理工艺。

The results show that matrix is mainly tempered martensite under the condition of quenching at low temperature and tempering at 550 ℃; retained austenite content increases and martensite content relatively decreases along with the increase of quenching temperature, meanwhile, the wear resistance improves.

结果表明：550℃回火条件下，低温淬火时基体组织以回火马氏体为主，随着淬火温度升高，残余奥氏体含量升高，马氏体含量相对减少，而耐磨性随淬火温度升高逐渐升高；
