钢材密度(Steel density) Calculation of density and quality of various steels The density of the steel is: 7.85g/cm3 Theoretical weight calculation of steel The unit of measurement for theoretical weight of steel is kg (kg). Its basic formula is: W (weight, kg) =F (basal area mm2) * L...
The Al- Zn- Mg- Cu series alloys has been widely used in the aircraft, automotive, ship- building and nuclear industries for the advantages of excellent combination of low density, high strength to weight ratio,good toughness and high co... J Zuo,L Hou,J Shi,... - 《Acta Metallurgica...
A four-fold increase in the strength after room temperature rolling suggests that the primary strengthening mechanism is related to the introduction of high density of dislocations and twins as observed in the TEM images. The enhancement in the strength from the as received condition to rolled ...
Lightweight aggregate concrete and limestone aggregate concrete with and without steel fibres were used in the study. The compressive strength of the concrete mixes varied between 90 and 115MPa and the fibre content was 1% by volume. Splitting tests on prisms and three-point bending test on ...

This contribution reports the results of the collaborative research unit SFB 761 “Steel — ab initio”, a cooperative project between RWTH Aachen University and the Max-Planck-Institute for Iron Research in Düsseldorf (MPIE) financed by the...
The martensite phase has high strength and hardness due to the solid solution, phase transformation strengthening and ageing strengthening effects as well as higher dislocation density [136–139], so the cutting forces increased with the increasing of martensite volume fraction in steels. Fig. 17 ...
