The specific gravitis of titanium and titanium alloy are small, and the strength of those are high. These materials are known as a form memory alloy that a form is returned to the original form after the deformation. Recently, this material has been used for the glass frame well by this characteristic. But, because press processing is difficult for these metals, only by cutting processing is done under the room temperature. And, discoloration due to heating of this material is a big problem and grinding after heating is difficult process, too. Therefore, many processes should be necessary presses processing under the high temperature of this material. For these reasons, processing by the press under the high temperature of titanium and titanium alloy is not utility technology.Presently, a press machine for processing the material for the glass frame under high temperature using the electric resistance of the metals is developed. And, titanium materials were examined about the mechanical properties after the pressure molding. At the result, it was found that pressure molding of these materials were possible by this method under temperature at the metamorphosis point.

钛及钛合金的比重小，强度高。这些材料被称为形状记忆合金，形状在变形后恢复到原始形状。最近，这种材料已经被很好地用于玻璃框架。但是，由于这些金属的冲压加工很困难，只能在室温下进行切割加工。而且，这种材料因加热而变色是一个很大的问题，加热后的研磨也是一个困难的过程。因此，在这种材料的高温下，许多工序都应该是必要的冲压加工。目前，研制了一种利用钛及钛合金的电阻对玻璃框材料进行高温加工的压力机。并对钛材料加压成型后的力学性能进行了测试。结果表明，该方法可以在变形点温度下对这些材料进行加压成型。
