In this work, the effects of micro-alloying Mn, Ni, and Si on microstructure mechanical properties high-carbon pearlite steels were investigated. The results indicated that addition solely Ni to pearlitic steel can enhance strength through refinement interlamellar spacing, but work-hardening in ferrite colony may be delayed, leading a reduction area. multiple additions increase Mn contents bene...

An experimental high strength steel weld metal containing 7 wt. % nickel and 2 wt. % manganese was found to have a complex microstructure. Employing high resolution characterisation techniques the microstructure consisted primarily of a mixture of martensite, upper bainite and a novel constituent with large grain size that contained plate-like precipitates. This constituent was characterised to...
