1. X-Ray
and Electron Microscopy Labs
In the X-Ray Lab chemical analysis and
phase identification are performed on a variety of materials including
metals, ceramics, polymers and composites. Chemical analysis of elements
with atomic numbers higher than 10 is possible using the XRF unit. Phase
identification and crystal structure determination are carried out using
X-Ray Diffractometer.
In the Electron Microscopy Lab, size,
morphology and distribution of phases, crystal structure, crystal
defects and phase transformation are regularly studied in different
kinds of materials. Nano-scale materials are also investigated using
PHILIPS CM 200 TEM/STEM unit.
Examples of services provided by
Electron Microscopy Lab are as follows:
- Study
of size, shape and distribution of phases in metals, polymers, ceramics
and composites down to nano-scale.
- Study
of crystalline defects such as dislocations, stacking faults and grain
boundaries.
- Study
of orientation relationship in multiphase samples.
- Study
of phase transformations such as recrystallization, precipitation and
martensitic transformations.
- Study
of deformed structures and micro-mechanisms of deformation.

Powder Metallurgy
and Technology Nano Structured Materials Rapid Prototyping and
Tooling
The research
center for nanostructured and advanced materials (RCNAM) was
formed in April of 2004 as an outgrowth of the Materials Science
and Engineering Department of Sharif University of Technology.
Its basic goal is to champion improvements in processing of
advanced materials through education, research, and service.
RCNAM is now actively involved in performing various industrial
projects through the appropriate contracts by the industries and
organizations in the country. The center is supported by both
public and private funds for doing basic and applied research
activities. It addresses the problems of the national and
international materials processing community and focuses on the
following research areas:
- Production and
processing of composite materials
- Nanostructure
materials, in particular nanoparticles and nanocomposites
- Science and
technology of polymers
- Tailored and
functionally designed materials
- Metal Foams and
cellular structures
- Friction and
anti-friction materials
- Biomaterials and
biomedical devices
- Advanced materials
deformation and forming processes
- Rapid fabrication of
prototype components and durable tooling
- Advanced magnetic
materials
- Mechanical alloying
and milling
- Computer simulation
and process control in support of materials processing
The goal of the CRNAM program is to put into place the resources
and training to advance the nanostructure and advanced materials
filed in a global, competitive environment. To this end,
education, research and service are all intertwined to complete
this task. We couple the educational component with an equally
strong hands-on laboratory experience for a balanced program.
This provides a good balance for basic and applied research.
