Plastic instability related to grain-boundary failure in an Al-Zn-Mg alloy at low temperatures
Abstract The strength and ductility of an Al-6 wt % Zn-1.2 wt % Mg alloy at low temperatures have been investigated by varying the grain size, the amount of grain-boundary precipitate and the nature of the precipitates in the matrix. Pronounced grain-boundary embrittlement has been observed at tempe...

| 520 | |a Abstract The strength and ductility of an Al-6 wt % Zn-1.2 wt % Mg alloy at low temperatures have been investigated by varying the grain size, the amount of grain-boundary precipitate and the nature of the precipitates in the matrix. Pronounced grain-boundary embrittlement has been observed at temperatures below — 100° C in alloys age-hardened by GP zones and especially in coarse-grained alloy specimens, but was not observed in over-aged specimens. From the condition for plastic instability related to the grain-boundary micro-cracking, the temperature and structure dependences of the ultimate tensile properties are expressed by; (σi − $ σ_{o} $)/$ σ_{i} $=εu/n + C, where σi is the instability stress (true ultimate tensile strength), σ0 the 0.2% proof stress, εu the uniform elongation, n a constant found to be about 1/2 and C a constant related to the work-hardening rate of the matrix. | ||

Plastic instability related to grain-boundary failure in an Al-Zn-Mg alloy at low temperatures |
| abstract |
Abstract The strength and ductility of an Al-6 wt % Zn-1.2 wt % Mg alloy at low temperatures have been investigated by varying the grain size, the amount of grain-boundary precipitate and the nature of the precipitates in the matrix. Pronounced grain-boundary embrittlement has been observed at temperatures below — 100° C in alloys age-hardened by GP zones and especially in coarse-grained alloy specimens, but was not observed in over-aged specimens. From the condition for plastic instability related to the grain-boundary micro-cracking, the temperature and structure dependences of the ultimate tensile properties are expressed by; (σi − $ σ_{o} $)/$ σ_{i} $=εu/n + C, where σi is the instability stress (true ultimate tensile strength), σ0 the 0.2% proof stress, εu the uniform elongation, n a constant found to be about 1/2 and C a constant related to the work-hardening rate of the matrix. © Chapman and Hall Ltd 1978 |
