IMI834 texture of titanium alloy and high temperature mechanical properties of the relationship
In the direction of the initial hardening riD higher. Material 1020cC hot, water quenching was significantly higher than the yield stress after air-cooled state. For example, in the RD direction of water quenching state d. Value of 595MPa, while the air-cooled state - 545MPa. At 98O ? or 95O ? hot material, and RD in the TD direction than the direction of higher plasticity. For example,alexa mulberry, hot-rolled at 950 ? 45. The direction of the high value of ductility with 0.69, while its direction is parallel to RD 0.5; parallel TIE) value of 0.62. Water quenching after hot rolling in 1020cC state of plasticity was significantly higher than air-cooled state. For example, the state parallel to the RD water quenching test is 1 +13; and air-cooled material is only 0.46. 2.4 bat changed test four different heat treatment (1020 ~ hot-rolled, 990 ?,ed hardy nederland, 8h/AC; 1020 ~ hot-rolled, 990 ?, 8h/wQ; 980 ? hot-rolled, 990 ?, 8h/AC; 950'E hot-rolled, 990 ?, 8h/AC) creep tests showed that at 600 ?, 210MPa of stress recrystallization followed by air cooling of the three states of the creep resistance similar to parallel to the RD and 45. The direction of the test results, the creep strain of about 0.6%. All three air-cooled state of the direction parallel to rid the sample showed a slightly lower creep strain (high creep resistance),mulberry norge, for example,mac cosmetics wholesale, 1020 ~ hot-rolled state,oakley solbriller, the creep value of 0.43%. Hot water quenched material by 1020'E state, compared with air-cooled state bar low creep resistance. If the RD direction, for the water quenched state creep strain of 1.57%,mac makeup wholesale, while the air-ling state was 0.58%. 2.5 Fatigue test high-cycle fatigue (HCF) testing on snapped, one (test temperature 600 ~ C,mulberry helsinki, load control R: 0.1) The results showed that l0 'cycle of all four states of fatigue strength (with RD or compared to TD direction) at 45. Direction is lower. Three kinds of air-cooled state of fatigue strength compared to that rolled at lower temperatures (980oC, 950oC) of the two materials (RD and TD direction) of the fatigue strength of about 400MPa; in the 1020 ~ C material than hot-rolled state low fatigue strength values: parallel TD of 390MPa. Parallel to the RD direction 375MPao for hot-rolled material at 1020 ~ C, air-cooled and water quenched state compared to water quenching state has a higher fatigue strength values. Zhang was arrested translated MetaUkd), 90 (1999) 3. P. 174-181 Medical implanted with pieces of fine grain titanium c. . 3 Los Alamos National Laboratory in New Mexico. Room of scientists, through the refinement of titanium metal emblem of the organization was to develop a manufacturing high-strength titanium doctors fall into pieces of technology. Titanium implant material for decades of history, but in recent years experimental results have proved that these titanium alloys are not suitable for bone tissue, and pure titanium comes in feasible. However, despite the titanium metal is chemically inert, and that are compatible with human tissue, but it was to teach organization coarse grains clearly a result of a lack of required strength. Component technology to solve this problem, Los Alamos National Laboratory researchers have developed such a fine grain structure of the titanium metal. The material has good adhesion and bone tissue of the advantages and strength better than coarse grain titanium. Although the FI) A proven titanium metal can be used for medical implants, but still plan to conduct some tests to make sure that the biocompatibility of ultrafine grained metal. Also intends this material for heart valves and pacemakers. Huang Yuanheng Zhaiyi Zi (ADVANCEDMATE.RIALS & PROCESSES). 11/99. P. 8 laser forming of titanium to aluminum compounds 7-TiM the base alloy has a high stiffness, good high temperature strength, low density, good oxidation resistance and flame resistance. Suitable for advanced turbine engines, aircraft and automotive components. It is usually casting, forging or powder metallurgy methods. As the difficult process of casting and poor, high production costs, passing rate is low. Pour the root sprouts Ken Hall Castle Hall once the amount of plastic dust dust barrier once the FredYolton and JohnMoll view, laser forming Co6,mulberry oslo, can overcome many of these difficulties, there may be a low-cost process.
