A metal alloy and includes an enhancement coating material.

A process for producing a glass melting component composed of refractory metal. A surface zone of the glass melting component is densified at least in sections by application of local compressive stress. As a result the surface zone has its porosity reduced compared to a volume section which is located underneath the surface zone and which has residual porosity.

Medical devices, such as implants, having a high-modulus alloy. The alloy includes a biocompatible refractory-metal-based alloy having multiple refractory metals. The alloy has an elastic modulus above about 300 GPa. The alloy comprises 30-35% tungsten, 60% molybdenum, and 5-10% niobium. The alloy is absent of rhenium.
