We can use them for biology medical materials, such as artificial bone and vascular prosthesis.
We also can use them for cosmetics and chemical materials[9-12].

Materials and Testing The materials for laboratory evaluation were acquired from Margalla hills and Dina quarries.
The test was performed on the materials passing 14mm sieve and retain on the 10mm sieve.
The Soundness test was also conducted on both the materials to check the materials resistance to intense weathering conditions (e.g Freeze/Thaw and attack by various salts etc).
The Dina materials show a bit low resistance to degradation and abrasion as compared to Margalla material but within the specifications for wearing and base materials.
The evaluation shows that Dina materials are suitable for road construction projects.

This has been acheived by the application of composite materials [8,9,10].

Unfortunately, chromium has a poor ductility at room temperature, mainly due to impurities like nitrogen or oxygen [[] Y.F.Gu, Y.Ro, H.Harada: The possibility of Cr-base alloys for high temperature applications, Materials Science Forum, vols. 475-479, 627-630 (2005) ], whereas at high temperature, its high creep rate limits its use in structural application [[] Y.F.Gu, Y.Ro, H.Harada: Chromium and chromium-based alloys: problems and possibilities for high temperature service, JOM, 56 (9) 28-33 (2004) ,[] C.L.Briant, K.S.Kumar, N.Rosenberg, H.Tomioka: The mechanical properties of high purity chromium, International journal of refractory metals and hard metals, 18, 9-11 (2000) ].
Materials The alloys were synthesized by melting metal pieces in a high frequency furnace in a chilled copper crucible.
The raw materials are of commercial-purity (>99.9%).
Journal of Materials Science, 38(9), 2063-2072 (2003) ] and giving the highest oxidation resistance was elaborated.
The elaboration of Cr-MoW alloys by melting is very difficult due to the very high melting temperature of the raw materials.

During repeated operations, personnel difference will induce operation differences, materials consumption of the smelting process fluctuates, and finally the cost of smelting fluctuates.
Statistical value of daily cost data N minimal value maximum value mean value standard deviation Steel cost 30 2355 3497 2923 224 Valid N 30 According to basic principles of smelting, material and energy balance was calculated; the amount of materials required per heat was counted out.
In one cluster, every heat has similar materials and smelting results, according to my theory above: the low-cost heat means the low-cost operation method, and operation parameters are summary out from data in the cluster.
As a new heat, materials have been prepared, and the target steel grade has been confirmed.
