Forming method for improving structure property of QAl10-4-4 aluminum bronze alloy cast ingot

The invention discloses a forming method for improving the structure property of a QAl10-4-4 aluminum bronze alloy cast ingot. According to the technical scheme, a sawn QAl10-4-4 aluminum bronze alloybar is heated to a preset high-temperature interval, heat preservation is conducted, and then cast ingot cogging forging is conducted; a blank obtained after ingot casting cogging is heated to a preset medium-temperature interval, heat preservation is conducted, and then intermediate procedure forging is conducted; a blank obtained after intermediate procedure forging is heated to the preset medium-temperature interval, heat preservation is conducted, and then final forging forming is conducted; and a blank which is finally forged and formed is annealed according to a preset temperature, andafter discharging and air-cooling, a finished product forging is obtained. According to the method, a forging with fine grains, uniform structure, high flaw detection level and good comprehensive performance can be obtained. 本
