合金元素对堆焊效果的影响的外文翻译
As Mo is a strong carbide-forming element,
the higher strength of Mo-added steels may be attributed to carbide
precipitates as secondary strengthener phase in the microstructure[18].
The Mo in solution effectively suppress the formation of embrittling carbide precipitates and pearlite,
even when austenite is exposed to high temperature (above 275 \x03C) during welding or during service.
The molybdenum in primary carbides tends to change morphology from continous envelopes around austenite dendrites to less harmful nodular form, especially when molybdenum
conten texceeds 1.5 % [17].
The EDAX analysis of the hardfaced alloy and base
metal was measured over area of 2 by 2 mm Table 10.
Considering case of sample 2 and sample 4,
where Si content is varied but at high Mo (5 %) content,
there is increase in hardness from 26 HRC to 31 HRC.
As per XRD as amount of Si is increased the number of phases formed
with Si is increased (FeSiC, CrFeS, Mn5Si3).
Low Si content (2 %) has low Si rich phases.
Increase in Si content decreases the hardness, the reason may be due to more number of Si precipitates formed which may be soft or increase in speed which may cause decrease in hardness.
Further, microstructure of sample 2 is coarse grained which has Si (5 %) compared to (2 %).
