quenching crack

Quenching Crack Analysis and Prevention Measures of Tap Shank

丝锥柄部淬火开裂分析及防止措施

Quenching crack deep and long, straight fracture , fracture surface without oxide color.

淬火裂纹深而细长, 断口平直,破断面无氧化色.

The equilibrium phase particles that induce the sensitivity of the quenching are not the direct reason that causes the alloy fracture; the microzone of PFZ around particles limits crack extension and coordinates deformation, this causes the formation of the ductile tension fracture.

引起淬火敏感性的平衡相粒子，不是造成合金断裂的直接原因，粒子周围的无析出微区起到了限制裂纹扩展和协调变形的作用，是合金形成延性拉伸断口的原因。

There are two kinds of the medium frequency quenching crack for the crankshaft, namely, cracks in both oil hole and neck surface.

曲轴中频淬火裂纹有油孔裂纹和轴颈表面裂纹两种。

The super high speed impact quenching was studied with experiment of crack arresting through pulse current discharge.

通过脉冲放电止裂试验研究了裂尖超高速淬火全过程。
