AA7050 was investigated by employing Jominy end quench test. The electrical conductivity measurement and microstructural observation were conducted at different distances from the quenched end. The results... precipitates were observed to nucleate on Al3Zr dispersoids when the distance from the quenched end was greater than 38 mm. Key words: Jominy end quench test; quench sensitivity; cooling rate; quench induced......
are feasible. The effect of the different combinations of these technological parameters on the microstructure can be mapped by the special Jominy end-quench test (so called intercritical Jominy end-quench test) described in this paper. Unlike the traditional Jominy test, in this case there is a partial anstenizing between A1 and A3 temperatures which results in a given amount of ferrite......
