The fourth-generation G4 metallurgy was a special silver-gold alloy used for recording studio cables where mechanical strength is very important. G5 was introduced in 2000, as a higher purity conductor for the
result in components that are often difficult and costly to manufacture. During machining, very high temperature is attained on the cutting edge of the insert due to the low thermal conductivity of the alloy and abrasive elements in its material composition. It encourages high wear rates...
Explain why hydrogen fluoride (HF) has a higher boiling temperature than hydrogen chloride (HCl) (19.4oC vs. - 85oC), even though HF has a lower molecular weight Van Der Waals Forces: Van Der Waals forces are relatively weak...
Determine the of number of phases of an alloy starting from the liquid to room temperature such as a Cu-Au, Pb-Sn, Fe-C, Fe-Fe 3 C,MgO-Al 2 O 3 phase diagram.A borosilicate glass has an annealing point of 544 C and a softening point of 780 C. What is the working...
A 65 wt% Ni-35% Cu alloy is heated to a temperature within the + liquid phase region. If the composition of the \alpha phase is 70 wt% Ni, determine: a) The temperature of the alloy, b)The compositio Explain why hydrogen fluoride (HF) has a higher boil...
The addition of sulfur to Monel R405 helps to improve machineability. This alloy grade is used to makevalvecomponents andfasteners. Monel 404 is generally suitable for electronic applications because it has lowpermeability. It is amenable to brazing. It contains a higher proportion of copper (47...
A number of publications have characterized low-alloy steel welds by specifying the power per unit length. This paper uses a 3D numerical model to compute the transient temperature and evolution of the microstructure in six welds with the same weld power per unit length of weld but with differen...
When using cutting fluids with硬质合金工具, the fluid must be applied continuously from start to finish to avoid causing cracks in the hard alloy blades due to sudden cooling. Cutting fluids should be kept clean and impurities should be minimized. Expired cutting fluids should be replaced in a ...
C12000 has less residual phosphorus than C12200, so its thermal conductivity are higher than C12200. Mainly used for pipe applications, such as gasoline or gas conveying pipe, drain pipe, condensate pipe, mine pipe, condenser, evaporator, heat exchange...
