“pearlite”造句，怎麼用pearlite造句

This paper studies the process of heat treatment of particle pearlite malleable cast iron by the way of microstructure.

A solid solution of ferric carbide or carbon in iron; cools to form pearlite or marten site.

Above this point the hardness can be increased only slightly, because steels above the eutectoid point are made up entirely of pearlite and cementite in the annealed state.

The resulting structure is a mixture of primary or pro-eutectoid ferrite (ferrite that formed above the eutectoid reaction) and regions of pearlite.

As before, any remaining austenite transforms to pearlite upon slow cooling through this temperature.

Results showed that warm deformation of pearlite will accelerate greatly the spheroidizing process.

It was found by experiments thatboron increased the growth rate of pearlite, both in hypoeutectoid and eutectoid steels.

A metastable aggregate of ferrite and cementite resulting from the transformation of austenite at temperatures below the pearlite but above the marten site start temperature.

Specialists suggested that they use pearlite to improve the structure of the building.

The results show that X80 pipeline steel obtains sorbite after quenching and tempering, gets pearlite by normalizing.

The result indicates that the fracture of pearlite low carbon ductile iron belongs to brittle fracture;

Via vacuum induction furnace and metallographical analysis, the effects of RE on the grain size of the austenite and distance of the pearlite laminae of high-carbon steel for heavy rail were studied.
