[0041] As noted, the static chamber insert 30, 60 is fabricated from a material having a high modulus of elasticity, defined herein as a modulus of elasticity that is at least 60.times.10.sup.6 pounds per square inch, and a sufficiently high yield strength. In some embodiments, the static chamber insert 30, 60 comprises a tungsten alloy, a bulk metallic glass ("BMG"), or other material exhibiting comparable elastic modulus and yield strength. For example, the static chamber insert 30, 60 may comprise one of a tungsten carbide and a tungsten heavy alloy. In certain embodiments tungsten carbide includes tungsten and carbon with tungsten comprising about 50-96% of the alloy. Other tungsten-based materials are contemplated including other ratios of tungsten-to-carbon and materials including about 0-20% of cobalt and other elements. A tungsten heavy alloy may be formed from about 80% or more of tungsten, about 90% or more of tungsten, or about 95% or more of tungsten. Such tungsten heavy alloys may include about 0-20% or 0-10% of one or more of iron, copper, nickel, molybdenum, or similar elements. A BMG is a type of amorphous metal alloy (i.e., having a disordered atomic-scale structure) that is based on one or more of zirconium, palladium, iron, titanium, copper, and magnesium. BMG typically is formed from two, three, four or more elements that are cooled with a disordered state instead of a crystalline structure. BMG is formed with a thickness of about 20-50 microns up to about 2 cm. “
