3. 結果和討論
3.1 顯微結構
3.1.1 改性對高鉻鑄鐵在澆築時顯微結構的影響
圖1示出了改性高鉻鑄鐵在澆築時的冶金顯微結構。圖1(a)-1(c)是在相同量的V,Ti和B時,分別用 0%, 0.4%, 和0.8%的不同RE含量下改性的高鉻鑄鐵的顯微結構。可以看出,高鉻鑄鐵的碳化物的形態和初生奧氏體受到稀土元素含量的巨大影響。如圖1(a)所示的那樣,沒有RE改性,高鉻鑄鐵的初生奧氏體發展成粗的枝晶,而碳化物生長成厚的板條。
圖1 澆築時改性高鉻鑄鐵的冶金顯微結構:(a)0% RE, 0.4% V, 0.3% Ti和 0.1% B; (b) 0.4% RE, 0.4% V, 0.3% Ti和0.1% B; (c) 0.8% RE, 0.4% V, 0.3% Ti和0.1% B; (d) 0% RE, 0% V, 0.3% Ti和0.1% B; (e) 0% RE, 0.4%V, 0.3% Ti和0% B; (f) 0% RE, 0.4% V, 0.3% Ti和0.1% B.

About Sheet Metal Fabrication Services

Sheet metal fabrication services providers manufacture components by cutting, bending, rolling, forming, stamping and welding sheet metal. Components manufactured through sheet metal fabrication services are used in a variety of applications such as enclosures, computer equipment, HVAC components, kitchen and sanitary equipment, machine tools and other instrial applications. Sheet metal fabrication services include a diverse range of processes used to fashion sheet metal into usable procts. These processes may be broken down into three rough categories, cutting, forming, and finishing services.

Sheet metal cutting services includes a number of techniques used to cut metal into smaller pieces so that it can be molded or formed into components. Common types of sheet metal cutting involve shearing, electrical discharge machining (EDM), laser cutting, water jet and abrasive cutting. Shearing uses a specialized machine to cut sheet metal by applying shear stress. This process is used to cut large sheets of metal into smaller parts. Laser cutting machines use laser light to cut or etch holes or profiles. Laser cutting machines are very precise programmable pieces of equipment. Water jets and water abrasive jets rely on highly pressurized water (20,000 - 60,000 psi) flowing through a nozzle or "jewel" approximately 0.010" in diameter. Advantages include almost no material heating ring cutting, low side loads, and ability to achieve complex shapes and tight inside radii. Low fixturing costs and fast setup and programming times make this process very suitable for prototypes or short runs. It is most widely used for two-dimensional cutting; three-dimensional machining is possible in specialty applications

Wire electrical discharge machining (EDM) equipment is used to cut conctive materials using a thin electrode. The electrode is a thin wire (typically .004"-.012") that follows a programmed path. The wire does not physically contact the part. It is charged to a certain level and surrounded by de-ionized water. A spark is generated that jumps the gap and melts a small amount of material on the part.

Sheet metal forming processes include those actions used fashion metal into specific shapes or semi-finished pieces. Common techniques include bending and forming, rolling, stamping, punching, welding, and hardware and fastener creation. Bending and forming processes are used to shape the sheet metal to its final shape. In the rolling process, a series of roll stands is used to progressively shape or bend a strip of flat-rolled metal to a desired cross section. Stamping is the process of impressing surface definition and three-dimensional designs onto materials with pressurized tools and dies. Punching is the process of punching holes in the sheet metal. Welding is the joining of metals and metal parts by melting and re-forming a metal bond between materials, with or without additional filler metal. Hardware and fastener creation is the capability to supply and integrate hardware such as handles, latches and threaded, self-clinching fasteners used to provide threads in sheet metal that is too thin or soft to be tapped.

機械工程師資格認證的有關要點
(詳細情況請在www.cmes.org網站上查看)

●機械工程師資格認證的標準是參照工業發達國家有關標准制定的。開展這項工作的主要目的是①為企業在人才的選擇上提供一個客觀的評價;②推進國際技術資格互認;③促進機械工程技術人員接受繼續教育,構築終身教育體系。
●我國現在還未加入相應的綜合性國際互認組織。中國科協正在啟動加入互認組織的程序。中國機械工程學會「資格認證」工作正是這一程序的一部分。特別是「高級機械工程師」就是瞄準將來與國際接軌而設定的。
●機械工程師資格認證實行資格認證、考試、培訓的三分離原則,面向社會體現公開、公平、公正;資格認證與繼續教育緊密結合,以真正體現專業技術人員的終身教育;進一步與國際接軌,力爭國際互認。
●中國機械工程學會開展的「資格認證」是非政府的中介組織行為,屬於同行認可的技術(或從業)資格認證。與現在人事部門「職稱評定」和有關部門「職業資格」不同。專業技術人員可根據自己的情況自願申請「資格認證」。
●取得「認證資格」有效期為三年。
●申請認證機械工程師應具備的條件
從事機械工程類工作的專業技術人員只要符合下列條件均可申請機械工程師資格認證。
要求本人具有良好的職業行為道德規范,並提供以下有效文件:
(1)畢業證書原件並保證真實性。學歷類別規定:A類:機械類大學本科及以上;B類:機械類大學專科;C類:非機械類工科大學本科及以上;D類:非機械類工科大學專科;E類:同等學歷。
「機械類」是指在大學期間學過機械原理、機械零件、理論力學和材料力學四門課程;「工科專業」教育部門對此有專門定義;「同等學歷」是指上述兩類以外的各類人員。
(2)外語要求具備下列之一:①國家外語四級證書;②人事部門職稱外語考試合格證書;③由分中心及我會認可的培訓機構培訓考核合格證書(此類證書需加蓋培訓單位和省學會章)。
(3)計算機要求具備下列之一:①計算機等級考試證書;②計算機應用技術三個模塊合格證書;③由分中心及我會認可的培訓機構培訓考核合格證書(此類證書需加蓋培訓單位和省學會章)。
(4)機械工程師「綜合素質與技能」考試合格證書。
(5)繼續教育要求具備下列之一:①國家認可的繼續教育證書(人事部門發放);②由分中心及我會認可的培訓機構培訓考核合格證書(此類證書需加蓋培訓單位和省學會章)。
(6)實際工作經歷,專科畢業4年以上(非機械類需6年),本科畢業3年以上(非機械類需5年),其中必須有1年以上在生產、科研企業工作經歷,同等學歷者須有15年以上的工作經歷。
(7)提供工作總結報告(由本人崗位上級寫出工作業績評語,並需經單位領導簽署意見及公章證明)。
(8) 工作年限要有相應證明材料。
