Mechanical properties of aluminum-phosphorous brass in temperature-rate loading

1. A composite investigation of the hardness, strength, and plasticity of the brass made it possible to more throughly study the process of deformation of the alloy in heating. 2. Despite the generally similar character of change in the nominal yield strength and tensile strength in relation to temperature, the values obtained for a deformation rate of 10−4 sec−1 in the 290–900°K temperature range are higher than for a rate of more than 10−3 sec−1. 3. For all of the deformation rates considered with an increase in temperature the strength and hardness of the alloy are controlled by the same mechanisms and processes respon sible for plastic deformation and successively replacing one another as for other fcc and bcc materials [9, 10, 13]. 4. The alloy possesses the greatest plasticity and least strength at a deformation rate of 2·10−3 sec−1, which may be preferred in setting up the production operations for working of it.
