The Role of Niobium in Superalloys

0 Comment

The Role of Niobium in Superalloys Refractory elements are important alloying additions in both nickel-base and iron-nickel-base superalloys. They are responsible for the increased high-temperature mechanical properties present in current superalloy systems. In this article, we’ll take a look at the role of niobium in superalloys. It has long been established that nickel-base and iron-nickel-base […]

Which Metals are Nickel Free?

0 Comment

Which Metals are Nickel-Free? In 1751, Axel Fredrik Cronstedt, working at Stockholm, investigated a new mineral – now called nickeline (NiAs) – which came from a mine at Los, Hälsingland, Sweden. He thought it might contain copper but what he extracted was a new metal which he announced and named nickel in 1754. Many chemists […]

Refractory Alloy Sintering Process

0 Comment

Refractory Alloy Sintering Process In today’s article, we’ll take a look at the refractory alloy sintering process. Refractory alloy sintering can be divided into six stages. Refractory Alloy Sintering Process – 1. Agent Removal & Burning Stage With the rising temperature, the molding agent gradually decomposes or vaporizes with the sintered body left. At the same time, […]
