WANG Yanbin , WANG Anrong , CHU Wuyang , XIAO Jimei University of Science and Technology Beijing , Beijing , China associate professor , Department of Materials Physics , University of Science and Technology Beijing , Beijing 100083 , China

金属学报(英文版)

The formation and aggravation of hydrogen damage in Fe-3 wt-% Si alloy during cathodic charging Were studied by means of Lange transmission X-ray topography.Results showed that hydrogen damage did not form in the specimens charged in 0.5 mol/L H_2S0_4 so- lution without poison,and occurred with addi...

NON-EQUILIBRIUM SEGREGATION OF Si ON Al-0.35 wt-% Si ALLOY SURFACE

CHEN Niug , YU Zongsen University of Science and Technology Beijing , Beijing , China professor , Department of Materials Physics , University of Science and Technology Beijing , Beijing 100083 , China

金属学报(英文版)

Si segregation was observed in the vacancy condensation pits,formed by supersaturated vacancies beneath the oxidation layer of Al-0.35wt-%Si alloy,by optical microscopy,X- ray photoelectron spectroscopy and microhardness tests.This phenomenon could only be explained by vacancy-Si complex inducing no...

BEHAVIOUR OF BORON SEGREGATION AT GRAIN BOUNDARIES IN BCC Fe-3% Si ALLOY

ZHANG Sanhong HE Xinlai CHU Youyi~* KE Jun University of Science and Technology Beijing , Beijing , China lecturer , Department of Materials Physics , University of Science and Technology Beijing , Beijing 100083 , China

金属学报(英文版)

The behaviour of baron segregation at grain boundaries in Fe-3% Si has been studied by means of particle tracking autoradiography(PTA).The results indicate that the tendency of equilibrium segregation of B at grain boundaries in Fe-3% Si is higher than that in austenitic alloys.No observable nonequi...

EFFECT OF COMPOSITION ON HYDROGEN EMBRITTLEMENT IN Ni-Fe FCC ALLOYS

HU Wei WANG Yanbin CHU WuYang XIAO Jimei University of Science and Technology Beijing , China Associate Professor , Department of Materials Physics , University of Science and Technology Beijing , Beijing 100083 , China

金属学报(英文版)

The ductility loss and threshold stress intensity,K_(IH)during hydrogen charging were measured for pure Ni and four Ni-Fe fcc alloys.The results show that ductility loss in 40Ni60Fe alloy and K_(IH)a 50Ni50Fe alloy have a minimum value.The variations of the amounts of hydride, hydrogen evolution and...

BEHAVIOUR OF VACANCY INFLUENCE DURING DIFFUSION IN METALS

ZHANG Sanhong HE Xinlai CHU Youyi KE Jun (T.Ko) University of Science and Technology Beijing , China Doctor , Department of Materials Physics , University of Science and Technology Beijing , Beijing 100083

金属学报(英文版)

The effects of vacancies on diffusion of interstitial and substitutional atoms as well asinteraction between them in metals were discussed.In the interstitial alloy,a coupling betweeninterstitial atoms and vacancy is interrelated through the reaction of formation anddissociation of complex.For subst...
