is the main constituent in titanium alloys, of course, but they can contain a
significant amount of other elements, which are added for a variety of
metallurgical reasons. The strength of titanium alloys can often be comparable
to steel, but they have the advantage of having only about 60% of the weight.
This article continues FORGE’s series on forging
materials. The first installment on nonferrous forging materials discusses
aluminum alloys that are used in forged components. A general description of
aluminum alloys is followed by details of their chemistry and microstructure.
In the first four articles in this series, the operation and use of four types of forging equipment – hammers, mechanical presses, hydraulic presses and screw presses – were reviewed. In this fifth and final article, a general comparison of these four types of forging equipment is made. Each type of equipment can perform well or poorly depending on conditions and circumstances. It is hoped that the comparisons made in this article will help readers select the right type of equipment for the specific job.
