| Abstract |
80Ni-20Cr electrical resistance heating alloys containing 1.0%∼2.78% Si and 0∼0.2% mischmetal were prepared, and their life cycle, microstructure, electrical resistance and mechanical strength were investigated. Investigating the effects of the added elements on the life of alloys, it was found that the significant improvements were observed as Si contents increase when there exists mischmetal. Effects of mischmetal addition through grain growth inhibition are also discussed. |
