耐脆裂性 的英文怎麼說
中文拼音 [nàicuìlièxìng]
耐脆裂性
英文
resistance to brittle fracture-
But when heavyly loaded, the former is far better than the latter. the wear resistance of za27 alloyed with mn is no obviously better than that of common za27 alloy. under the sliding friction conditions, the wear resistance at high temperature of za27 is improved by alloyed si and reaches the highest level when the content of si is 1 - 3wt. %
裂紋主要始於脆性相si相和mn相，裂紋沿晶界擴展；在滑動摩擦條件下（常溫） ，含si的za27合金在載重較小時，耐磨性與普通za合金相比沒有明顯提高，但在載荷較大的情況下，其耐磨性遠高於普通za27合金材料；加mn的za27合金與常規za27合金相比，耐磨性沒有明顯提高；在滑動摩擦條件下， si的加入提高了za27合金的高溫摩擦性能。High chromium cast iron has higher erosion resistance at lower impact angle, while the erosion resistance is worse for the lower toughness at normal impact
高鉻鑄鐵在低角沖蝕時有較高的耐沖蝕性，但高角沖蝕時由於脆性大，易崩裂。Products function : put our “ sun shine ” brand carbon steel fiber evenly seep into concrete to form steel fiber reinforced concrete and it can decrease the thickness of reinforced concrete by half, it not only shorten the project time, save the material and manpower expense, bring distinct economic benefit, but also increase the performance of crack resistance, percussion resistance, tensile strength, bend resistance. scosspr resostamce amd wear resistance of the reinforced base materials. if the weight ratio of 2 % steel fiber seep into the concrete, it can solve the brittleness problem of the concrete, in the condition of 60 % ralative air humidity, after 21days air - dry, even 520 days air - dry, it ' s difficult to find any crack by eyesight, the bend resistance for the steel fiber concrete is 140 times stronger than the concrete without steel fiber, the capability of impact resistance increase 10 times
產品功能：將本公司「雙興」牌碳鋼纖維系列產品均勻地摻入混凝土中，形成鋼纖維增強混凝土，可使工程中鋼筋混凝土的施工厚度降低一半，不僅縮短了施工工期，節省了材料和人工費用，帶來顯著的經濟效益，且增強了基體的抗裂、抗沖擊、抗彎、抗剪、耐磨擦等性能，如摻入本公司2 %鋼纖維的混凝土，不僅解決了混凝土的脆性問題，在空氣相對濕度60 %的條件下風干21天後，甚至在風干520天，肉眼很難發現裂縫，摻入鋼纖維后的增強混凝土比不摻鋼纖維的混凝土抗彎強度提高140倍，耐沖擊荷載提高10倍。Testing of high - strength steel building elements for resistance to hydrogen - induced brittle fracture and advice on the prevention of such fracture
高強度結構鋼部件耐氫誘導易脆斷裂的特性.用支柱試驗The research of high performance pavement concrete ( hppc ) is done in two sides. one is mixture design, the other is pavement performance. the mixture design and design flowchart of hppc is given on the base of nc with the consideration of characteristic of both hppc and nc. the grow law, influencing factor and formation mechanism of hppc strength is analisised by perpendicular experiment. in the same, the fatigue equations are set up for hppc and hppc i on the base of fatigue experiment. the fatigue mechanism of hppc is analysised by damage mechanics and fracture mechanics. brittleness, frost resistance and abrasion resistance of hppc is researched with the camparition to nc i. at last, the economic analysis of hppc is done by two kinds of way
結合高性能混凝土與普通路面混凝土的特點，提出了建立在普通路面混凝土基礎上的高性能路面混凝土配合比設計方法，給出了設計流程；通過正交試驗（強度試驗） ，分析了高性能路面混凝土的強度發展規律、影響因素與形成機理；同時，根據疲勞試驗結果採用雙參數weibull分佈模型分別建立了高性能路面混凝土和高性能路面混凝土（沒有摻加硅粉）疲勞方程，應用損傷力學和斷裂力學，分析了高性能路面混凝土的疲勞機理；並採用了對比分析方法，研究了高性能路面混凝土的脆性、抗凍性和耐磨性等。Pvc inline screw thread metal steel wire reinforced tube with even smoothy tube wall and advantages of withstand voltage, corrosion proof, acid alkali resistant, excellent bending property and unease aging, ect. it can replace ordinary rubber reinforced pipe, pe pipe, soft rigid pvc piep and partial metal pipe
具有耐壓耐油耐腐蝕耐酸堿，可屈撓性好，不脆裂不易老化等優點，可代替普通的橡膠增強管pe管軟硬pvc管及部分金屬管。The experiment test results of mechanical properties and durability of hprrc show : no matter at early age or later age, the ration of flexural strength to the cubic compression strength of hprrc is higher than ordinary concrete, and the brittleness of hprrc is reduced ; the bond performance of new - old concrete interface and chloride permeability are good ; its resistance to freeze and thaw, permeability are all excellent ; its volume stability is improved, and its cracking resistance is good
