This article focuses on dry cutting for ZGMn13 high manganese steel and through plenary academic analysis and scientific experiments, to improve Carbide drill with Multi-facet on the geometric parameters and the structure.

Tool life test of the carbide cutter(YT767)milling the difficult-to-cut material ZGMn13 high manganese steel by using the multi-factor orthogonal experiments is carried out.

Study on Experiment of Tool Life Test for Milling of ZGMn13 High Manganese Steel

Study on Toughness-Brittleness Transition of ZGMn13 Steel;

Superficial view of machining features of ZGMn13 high-manganese steel;

This paper presents related technical matters about high-manganese steel frogs'deposit welding,in- cluding the characteristics of various deposit welding techniques,mechanical properties,weldability and defects of high-manganese steel frogs,deposit welding technology,the choice of welding machines and welding rods and its application in production.

The high chrome cast-iron added a variety of drib and microscale elements was used to make the flat hammer in overpressure turbine crusher,which can improve the wearing resistance and synthesize mechanical property of the products greatly,and the life of the products is 4 times longer than the former high-manganese steel.

Using cumulate-welding technology,a layer of WC hard metal was compounded on the matrix surface of hadfield steel,and high wear resistance and high toughness WC/Mn13 composites was successfully fabricated.

The hardness change of cold rolling hadfield steel with different deformation was tested,through the cold rolling deformation of hadfield.

A nano scale grains surface layer on Hadfield steel was produced by shot peening treat- ment.

Cutting experimental study of new material tools for austenitic manganese steel riding wheel;

The cutting contrast experiments of austenitic manganese steel with compound SiC, compound Si3N4 and TiN coated carbide are researched.

The cutting experiments of austenitic manganese steel, which serves as large riding wheels at opencut coal mine,were carried out using different cutting tools.

The work hardening ability of ZGMn18Cr2Mo superhigh manganese steel has been investigated, the microstructure of the dense dislocations, some stacking faults, great amount of deformation twins, some intersecting twins and ultrafine carbides in a nano-scale has been observed under the condition of small scale uniaxial compressive deformation.

The experiment shows that the rapid pinning of a large amount of dislocations and the existance of fine deformation twins and some crossed tiwns are the major factors contributing to work hardening of superhigh manganese steel when deformed under relatively strong impact.

The influences of cryogenic treatments on the microstructure,material performances and the impact wear resistance of the superhigh manganese steel are studied.
