Bài giảng Vật liệu học: Chương 1 - Trần Thị Xuân

Materials science is an interdisciplinary field fundamental to understanding how the internal structure of materials dictates their observable properties and performance in various applications. This academic module, MSE2228. VẬT LIỆU HỌC, provides a foundational exploration into this critical area, highlighting the intricate relationships between a material's atomic arrangements, processing methods, and its ultimate functional characteristics. The study of materials is paramount for engineers as it empowers them to design, select, and develop advanced solutions, ensuring optimal performance and reliability across diverse technological domains, from basic construction to advanced high-tech components.

The MSE2228. VẬT LIỆU HỌC course offers a comprehensive introduction to the foundational principles of materials science and engineering. It systematically explores the "vai trò của vật liệu" by establishing the crucial connections between their inherent structure, properties, processing, and overall performance. The curriculum is structured to guide students through key concepts, beginning with the atomic structure and various types of bonding, followed by an in-depth analysis of crystalline structures, including the "mạng tinh thể" concept, unit cells, and the classification of "7 hệ tinh thể." A significant portion is dedicated to understanding "cấu trúc tinh thể của vật liệu kim loại," detailing how atoms arrange themselves in solids, the concept of amorphous solids, and the use of "Chỉ số Miller" for precisely describing crystallographic directions and planes. Furthermore, the course delves into quantifying the packing efficiency of atoms through "mật độ nguyên tử" (atomic packing factor) and examines typical crystal lattices like the Body-Centered Cubic (BCC) structure, providing real-world examples. Subsequent topics cover "cơ tính vật liệu," "hợp kim" and "giản đồ pha," "nhiệt luyện thép," and general "vật liệu kỹ thuật." The course employs a pedagogical approach combining lectures and recommended textbooks to ensure a robust understanding of how fundamental material science concepts underpin practical engineering applications and material selection. This holistic approach ensures students grasp the logic behind material behavior and develop skills to apply this knowledge in various industrial contexts.
