Through analysing the effects of grain size and temperature on the strain rate of superplastic aluminium composites and several other kinds of superplastic aluminium material, it is clear that microstructure is related to the superplastic test temperature. The more thermally stable microstructure, the ...
Strain rate effects on mechanical properties in tension of aluminium alloys used in armour applicationsThe mechanical properties in tension of two aluminium alloys (AA5059-H131 and AA7039-T651) used in armour applications were determined from tests carried out over a wide range of strain-rates on...

In literature, despite significant prior research conducted under quasi-static conditions, there remains a gap in understanding the dynamic behavior of AM materials. This review paper provides a comprehensive analysis of recent investigations into the high-strain-rate response of various metallic materials...
The high strain rate and high temperature properties of as cast and aged 7075 aluminium alloy were examined by metallographic observation and by means of a split Hopkinson bar test at temperatures between 25 and 300掳C and at strain rates of 1路3 103 and 3路1 103 s-1. The effect of ...
High rate of strain characterisation (102−−104s−1) commonly uses the Split Hopkinson Pressure Bar (SHPB). Developed by Kolsky15, the apparatus saw several enhancements to cater to a broader class of materials—metals, concrete, adhesives, composites31,32,33. Grote et al34have employed ...
7.3.2. Strain hardening rate in Stage I In Stage I, where secondary slip activity is not present, strain hardening rate in pure Fcc metals is governed by the unscreened ripple in the internal stress resulting from the rate of mutual trapping of edge dislocations into multipolar braids. Since...
As strain rate was increased above QS loading, both alloys exhibited significant increases in ductility. Reasons for the higher strains to failure at elevated strain rates are uncertain at this time; however, this phenomenon References (24) W.S. Miller et al. Recent development in aluminium ...
