A New Analytical Expression for the Relationship Between the Charpy Impact Energy and Notch Tip Position for Functionally Graded SteelsH.Samareh Salavati Pour1,2,F.Berto3,Y.Alizadeh11. Department... between the notch tip and the position of the middle phase in the FGSs on the Charpy impact energy is investigated in the present paper. The results show that when the notch apex is close to the middle......
210016, China) Abstract: A dendrite grain growth model that is based on cellular automaton method was developed and applied to simulate the columnar dendrite grain growth during the directional... conditions on the dendrite morphologies and solute segregation were considered. The results indicate that the solute of high concentration liquids is easy to concentrate in the closed or semi......
the coefficients of the denominator and numerator polynomials are affine in a real uncertain parameter vector δ satisfying the Euclidean norm constraint ||δ||<δ. The concept of stabilizability radius of P(s, δ) is introduced which is the norm bound δs for δ such that every member plant of P(s, δ) is stabilizable if and only if ||δ||<δs. The stabilizability radius can be simply interpreted as the ‘largest......
Effect of sample diameter on primary and secondary dendrite arm spacings during directional solidification of Pb-26wt.%Bi hypo-peritectic alloyHU Xiaowua,YAN Honga,CHEN Wenjingb,LI Shuangmingc,and FU... and secondary dendrite arm spacings,control the segregation profiles and the formation of secondary phases within interdendritic regions,which determine the properties of solidified......
The 3-dimensional morphology of dendrite during equiaxed solidification of an Al-5 wt.% Cu alloyXiaoping Ma,Dianzhong LiShenyang National Laboratory for Materials Science, Institute of Metal Research... of equiaxed dendrite was observed. The slim primary stem and secondary branches constitute the frame of dendrite, and rows of dense tertiary branches further divide the 3-dimensional space......
Primary dendrite growth kinetics and rapid solidification mechanism of highly undercooled Ti-Al alloysZ.C.Luo,H.P.WangDepartment of Applied Physics, Northwestern Polytechnical University摘 要:dendrite growth......
the two wick structures was explored. A theoretical capillary force model of skew-grooved wick structure was also developed to calculate its effective capillary radius by comparing with the rectangle... the skewed-grooved wick has a smaller effective capillary radius, its maximum capillary force is 8.64% larger than that of the rectangle-grooved wick. The results indicate that the skew-grooved wick......

Quartz......
A novel diffusion model considering curvature radius at the bonding interface in a titanium/steel explosive clad plateHai-tao Jiang1,Qiang Kang11. National Engineering Research Center for Advanced... of various factors, including the curvature radius of the curved interface, the diffusion coefficient, the heating temperature, and the holding time. The experimental results show good agreement......
Prediction of Dendrite Orientation and Stray Grain Distribution in Laser Surface-melted Single Crystal SuperalloyGuowei Wang1,2,Jingjing Liang1,Yizhou Zhou1,Tao Jin1,Xiaofeng Sun1,Zhuangqi Hu11... was taken into consideration in this research. The experimental results demonstrate that the simulation model applies well in the prediction of dendrite growth direction. Moreover, the prediction of stray......
