The Refractory alloy sintering can be divided into six stages. 1. Agent Removal & Burning Stage With the rising of temperature, the molding agent gradually decomposes or vaporizes with the sintered body left. At the same time, the molding agent more or less adds carbon to sintered body. The rising amount of carbon changes with […]
Sintering is a hot processing method to produce refractory metals. First, heat the powder compact to the sintering temperature for a certain period of time. Then, wait it to cool down and the refractory materials with required functions will be produced. Sintering makes the porous powder compact into a product with certain structures and properties. […]
Refractory metals are referred to elements or alloys with melting points over 3002℉, such as tungsten, molybdenum, tantalum, niobium, titanium, zirconium, hafnium, vanadium, chromium, rhenium and alloys including tungsten alloys, molybdenum alloys, niobium alloys, titanium alloys, vanadium alloys, chrome alloys, rhenium alloys, chromium and zirconium alloys, tantalum and button alloys, etc. Refractory metals usually can […]
