Course detail

Metal and Wood Materials

FAST-BJ08Acad. year: 2012/2013

For metals, the students get knowledge about physical and mechanical properties of ferrous and non-ferrous metals, the technology of production of pig iron, steel and cast iron will be explained. In addition, students will get conception of steel composition and steel alloying technology; based on the Fe-C diagram they will get the details about the basis of thermal treatment of steels.
For wood, the students get knowledge about various materials (wood, agglomerated wood-based), followed by a description of the macroscopic, microscopic and ultra-microscopic structure of wood, taking into account the basic chemical composition. Students will gain an overview of the basic physico-mechanical properties of wood and the basic defects of wood products will be presented.

Learning outcomes of the course unit

Obtaining the comprehensive knowledge of the structure material of metals (ferrous and non-ferrous metals) and wood should be considered as main result of the course. After finishing the lectures of the course, students should get the knowledge about the macroscopic and microscopic level of these concerned materials. Furthermore, they should have to get knowledge about the main types of wood finishing process and what lumber (timber) products are used in civil engineering industry. They should know the main parameters and properties (physico-mechanical) of the above mentioned materials. They should be able to describe the moisture effect on wood structure with respect to volume changes of wood, additionally to describe sorption process of water binding the cellular structure of the wood. Further, they have get the knowledge about the production of pig iron, steel and cast iron; describe the Fe-C diagram and have to know labeling of steels and methods of their heat treatments.

Prerequisites

Knowledge of basic, physical-mechanical properties of metals and wood, main products of these materials used in the civil engineering industry, elementary knowledge of wood and metal composition.

Co-requisites

Thermal properties,

Planned learning activities and teaching methods

The content of the lectures is prepared in the digital form of presentations with the largest share of graphic details that will allow to closer understanding the objective issue. The content of exercise lectures is based on the digital presentation of task, which is then clearly undertaken by experiment and then student must compile and evaluate the results in the reports.

Assesment methods and criteria linked to learning outcomes

To successfully complete the exercising part of course, each student has to be responsible to submit all finished reports that have been continuously monitored during the semester. Furthermore, the exercise lectures end with a test summarizing the tasks performed during the period. Lecture block is finished by the examination consisting from written and oral parts.
