In this fifth edition we have retained the objectives and approaches for teaching materials science and engineering that were presented in previous editions. These objec- tives are as follows: Present the basic fundamentals on a level appropriate for university/college students who have completed their freshmen calculus, chemistry, and physics courses. Present the subject matter in a logical order, from the simple to the more complex. Each chapter builds on the content of previous ones. If a topic or concept is worth treating, then it is worth treating in sufficient detail and to the extent that students have the opportunity to fully understand it without having to consult other sources; in addition, in most cases, some practical relevance is provided. - Ushbu beshinchi nashrda biz oldingi nashrlarda taqdim etilgan materialshunoslik va muhandislikni o'qitishning maqsadlari va yondashuvlarini saqlab qoldik. Bu maqsadlar quyidagilardan iborat: Birinchi kurs talabalari hisob-kitob, kimyo va fizika kurslarini tamomlagan universitet/kollej talabalariga mos darajada asosiy asoslarni taqdim eting. Mavzuni mantiqiy tartibda, oddiydan murakkabroqgacha taqdim eting. Har bir bob avvalgilarining mazmuniga asoslanadi. Mavzu yoki kontseptsiyani ko'rib chiqishga arziydigan bo'lsa, uni yetarlicha batafsil va o'quvchilar boshqa manbalarga murojaat qilmasdan to'liq tushunish imkoniyatiga ega bo'lgan darajada ko'rib chiqishga arziydi; bundan tashqari, ko'p hollarda, ba'zi amaliy ahamiyatga ega.
