Development of Microalloyed Intragranular Ferrite Steel With High Strength and Toughness;

A Study on Decarburization Trend of New High Strength and Toughness Spring Steels 40T and 44T;

Composition、 mechanical properties and wear-resistance of Zn base alloy with high toughness;

Bainite alloy steel rail and fork-rail with high strength and high toughness of which tensile strength in hot-rolled condition can reach up to 1250 MPa,25% higher than that of U75V,and impact toughness of rail waist is above 30 J/cm2,3 times higher than that of U75V.

However it was discovered after analyzing the properties measurement results obtained in the production of high toughness ADI that,with increasing of their tensile strength from 908MPa to 1054MPa,the elongation,impact toughness,yield strength and hardness of alloyed high toughness ADI castings did not change such obviously as f.

The primary factor showing ultra-high toughness of Panjin copolymer of polypropylene was revealed.

Research on Top Coal Cavibility and Control of High Ductility Very Thick Seam in Top Coal Caving Mining;

The experiment studied the characteristics of the chemical composition, heat treatment and melting of the high ductility ADI.

Reactive powder concrete is a cementitious material with Ultra-high performance,such as high strength、high ductility and low permeability.

This article tells of the main effecting factors on the manufacture of PP blends with high flowability and super high toughness, paricularly including the effect of the sort of matrix and talc content used in the blends.
