Alloying elements on the high speed steel of eutectic carbides
The original increase was due to w in Nan | c applications have a higher carbon content, and Mo in the M = C has a higher carbon content. Because the same carbon content in steel, Me, to a certain extent, C and V Mc carbide formed after the first. The remaining less than the formation of more Mc carbon carbide, carbide Mc therefore to a certain number of the ratio of tungsten and molybdenum (tungsten molybdenum high speed steel) of the maximum, and then further increased when Mo,[link widoczny dla zalogowanych], MtC but reduced when the number of carbide steel w decreased, Mo content increases, the eutectic reaction but before the transistor was more fully, the remaining liquid quantity small black saddle, muscle leaving the total eutectic carbide decreased. 2V on the total quantity of toxic carbon 2. \Mo / (w +2 Mo) on the Me carbon billion surplus property lWMo of U = 'tI-2Mo) Tin 5W, Mo of M. c Carbides U = M (W +2 Mo ring 6W, Mo compounds of breaking the clamor Mc v ring and on the total amount of eutectic carbide MtC, Mc and Mc carbide has a significant effect on the number of Organisation. V in addition to significant increase in the number of Me carbide, but significantly reduced the number of Mtc carbide (Figure 7- , increasing M, c the number of carbide (prince Yu 6). V for a total amount of eutectic carbide 29 - the impact of deposit steel, tungsten and molybdenum in different proportions are different l, w High Speed Steel (w ≤ 9, Mo ≤ 3) when v grub brief. eutectic tungsten carbide Yak huge lines and reduce the total amount of molybdenum high-speed steel towel when increasing v , increased the number of eutectic carbide Yun (Figure 9). v lj was changed at the shape of eutectic carbides old,[link widoczny dla zalogowanych], by: the size of carbide, carbide increases from v to snail-shaped bone to lamellar transition. with v is 3 to 4 pm. large number of MC carbide was increased. W, Mo and V oxides on eutectic He is the shadow of the high number of steel components of the station manager left, get on the favorable performance of organizations is important to Tanzania . M6C, MC and MC carbides form from the Yuan to their differences in the structure of their high-speed copper performance counters are not the same. Mc carbonation turn closely linked to internal and external iliac. forging easily broken. no man has been favorable carbon grid material distribution. MC carbides between the lamellar carbide films with weak, forging pieces with the ambassador, the other, Mc carbonation trowel is a metastable phase,[link widoczny dla zalogowanych], in the heating process out to decompose, so carbide thin ' ) TV on the MC carbide ring of Figure 8V MC carbides on the impact (on the next page the first 2o) IV Conclusion V (%) Figure 9V impact on the total product of the total gadfly. Therefore, the MC lamellar eutectic carbide is easy to obtain a favorable sub-carbide distribution. Molybdenum tungsten carbide high speed steel Mzc more because of the north, easy-to-be derivative} favorable carbide distribution on the performance. v content was 1 ~ 2, MC carbide size smaller,[link widoczny dla zalogowanych], all sentences for the distribution of the saddle; V content is less than a eutectic carbides are dominated by bone, forging unbreakable; V is greater than 3:00 with a large water lizard Soft c block significantly increased the number of carbides, so from a performance consideration, common high-speed steel in the volume V 2 is appropriate to the high content of vanadium high speed steel v 3, four conclusions about appropriate content is less than 1V l, different tungsten trial of high-speed steel, molybdenum ratio of eutectic carbides are mainly M. c; 2 by Mo eutectic carbide volume by reducing w, MC carbides increased, tungsten molybdenum high speed steel carbide Nie MzC more,[link widoczny dla zalogowanych], 8V is not only conducive to the formation of MC carbides, and obvious, but the Mc carbide formation, inhibit the formation of carbides Msc. l tempering condition, needle-like cracks in the Department of composite tissue phase interface through the expansion and cut along the cable for the body and change: granular composite maggots organization of the crack extension only along the phase interface; large particles pull Recovering maggots organizations in the cleavage crack Zeyi way through iron chain body. 2 low-temperature tempering state, no matter what form the composite tissue, they were all split twisted itself through the ferrite to form a cleavage fracture of a reference 1 3O Guo Kozo.
