Result and Analysis - EDS
□ Composition Analysis
Al, Si is almost insoluble to each other at rsoom temperature.
All solid phase will have either 100% Al phase or 100% Si phase.
Keff, Km, Kp : the effective thermal conductivities of the composite,
Metal matrix, Particles
φp : the volume fraction of reinforcements
a : the diameter of the reinforcement
- hc : the boundary conductivity.
Advantage
The air travels across the short
length of the fins laterally, rather than longitudinally down
the long length.
Focused on placing
이러한 관점에서 Pb Solder는 Pb의 매장량이 높고, 결착성이 좋으며 가장 좋은 특성으로는 낮은 융점 때문에 Pb Solder의 사용이 널리 퍼져 있었다. 사실 접합부에 Pb를 사용하는 것은 전도도가 좋기 때문은 아니다. Pb의 전도도는 Cu의 7%밖에 되지 않는다. 그러나 Pb를 사용하게 된 이유는 역시 대량 생산제품의
resulting nanocomposites. However, the effective thermal conductivity of carbon-based nanocomposites is strongly influenced by the Kapitza interfacial resistance.
In this study, a comparison between carbon nanotubes and graphene sheet nanocomposites that takes into account dispersion patterns of the nanoinclusions and the Kapitza resistance is performed by means of a Monte Carlo simulation.
properties.
Because of the extraordinary range of properties of polymeric materials, they play an essential and ubiquitous role in everyday life. This role ranges from familiar synthetic plastics and elastomers to natural biopolymers such as nucleic acids and proteins that are essential for life.
Most commonly, the continuously linked backbone of a polymer used for the preparation of plastics c
